To all whom it may concern:

Be it known that I, LONNIE A. BAX'i in, a. citizen of he United States of America, residing at ijincinnati, in the county ct Hamilton and State of Ohio, have invented new and useful Improvements in Vacuum- Cleaners, of which the following is a specification.

'.his invention relates to vacuum cleaners, and has for an object to provide apparatus of this kind designed for use in removing dust, etc, from floors, carpets or other sur faces and to further provide in the construction of the apparatus means whereby it may be manuaily propelled and operated by a single person.

Another object of the invention is to provide an improved form of dust chamber constructed with a view of simplifying the emptying of the collecting bag.

In the drawings, forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views:F-igure 1 is a perspective view showing in full lines the position of the apparatus on the out-stroke and showing in dotted lines the position of the appal'atus on the instroke. Fig. 2 is a longitudinal section through'the apparatus. is a section through the outer end of the dust chamber and through the connecting plate of the suction nozzle. Fig. 4 is a perspective view of the agitatolt.

The apparatuscomprises a pump 1 embodying substantially identically constructed members 2 and provided at their inner ends with peripheral flanged portions 41. The members 2 and 3 of the pump are separated from each other by the diaphragm This diaphragm may be of leather. rubber or any suital'le well known material which may be found best adapted for the purpose intended. The outer edge of the diaphragm is secured by rivets or equivalentfastening devices 7 between the peripheral flanged portions 4 of the pump members 2 and 3. The diaphragm actuating rod 8 extends through the head 3 of the member 2, and as illus trated, the inner end of the rod is provided with companion disks 9 arranged in clamping engagement against the opposite sides of the diaphragm and which are securely held to the rod by the adjusting nuts 1G. The disks 9 are provided with oppositely flared outwwnrdly e tions 11 which are c signed to prevent cut.-

The dust chamber 17 preferably comprises an elongated tubular structure secured in any suitable manner at its inner end to the pump members 2 and 3.

Atthe outer end, the dust chamber 17 is formed to provide an internal shoulder 18 againstwhich is seated a gasket 19, as shown. The shoulder 18 is provided with inwardly extending lugs 20 in which threaded. pas sages 321 are formed. These passages receive the clamping screws 22 on the attaching plate 28 which operate to hold the plate securely against the packing so as to provide a perfect air and dust-tight connection between the plate and the dust chamber. One of the lugs is provided with an opening 2st in which is seated a projection 25 on the inner face of the plate The plate 23 is provided with a conveying tube 26 which is attached to theneck 2. of the section nozzlehead 28. The head 28 may be of any suitable well known tornn but as shown, it is provided with a relatively long surface con tacting :tace 29 which may be moved across the surface to be cleaned when the cleai'iing apparatus propelled.

The apparatus herein described is provided with a handle 30 embodying a fixed side member 31 and a movable side member of the handle is secured to the extension 33 on the section 3-1 of a clamping band 35 around the chamber 17 at the inner end thereof. The intermediate portion of the fixed side member of the handle is secured to a .suitable bracket 36 which extends outwardly from the member 2 of the pump. The movable member of the handle has its outer end pivotally connected to the extension 36 of the section 3-1 of the clampingband, and as illustrated, the said. movable member of the handle is he outer end of the fixed side member provided with a bracket 37 to which pivinediately adjacent to the shoulder 18, is formed to provide a continuous groove 38 in which the spring ring 39 of the dust-collectw This construction permits of the bag being securely applied to and held opcratively associated in the cham her. The inner closed end of the bag is pro "vided with a rod etlv whose outer end is disposed in such proximity with respect to the outer end of the chamber as will permit it to ..e grasped conveniently when the nozzle plate is removed'from the dust chamber, thereby enabling the operator to completely out for the purpose of ejecting the accumulated dust.

In operation of the apparatus, the memhers 31 and 32, of the handle are grasped in the hand of the operator, as clearly illustrated in Fig. 1 of the drawings, the operator holding the handle members in position for the forward stroke. The operator sired suction in the dust chamber and in the nozzle head. The operator after complet- I ing the forward stroke moves the apparatus back to the first position, which imparts reverse movement to the diaphragm.- It will be understood that a continuous operation of the apparatus, as described, will createla continuous suction in the nozzle head so that an effective collection of the dust will be made in all positions of-the apparatus in its movement.

An agitating or shaking device 42 is located within the dust chamber. This device preferably comprises an arm 43 which is connected with the dust chamber by means of the fastening 4A, the connection bein h as to permit the device to be moved into contact with the bag so as to shake the out of the fiber of the bag and to provide for a perfect free air passage between the fiber of the bag and ducts, movement of the device being obtained Wholly by the air suction. The inner end of the arm is provided with a substantially arcuate head 45 which conformssubstantially with the curvature of the dust chamber.

1. The combination with a dust collecting chamber, of a vacuum cleaner, of a flexible bag located in the chamber, and an automatic oscillating agitator mounted in the chamber and disposed at one side of the bag, and contacting with the bag to shake the same when suction is applied to the chamber.

2. In a dust collector, a cylinder, a head closing one end of the cylinder, a fabric dust collecting sack mounted in the cylinder and expansible and collapsiblewhen suction is applied to the cylinder, an oscillating beater movablyinounted in the cylinder and adapted for beating contact with the sack on expansion and contraction thereof.

3. In a dust collector, a cylinder, a head closing one end of the cylinder and removably fitted thereto, a fabric dust collector sack mounted in the cylinder and expansible and collapsible when suction is applied to the cylinder and an ably mounted in the cylinder, and a withdrawing rgd secured to the closed end of the l sack andhaving a manipulating portion disposed ih roximity to the head whereby the I rod may lie engaged by the hand and Withdrawn from the cylinder when the head is removed so that the bag also can be partly Withdrawn from the cylinder to discharge the dust therefrom. In testimony whereof I affix my signature presence of two witnesses.
